The improvement of hydrogen storage characteristics by substituting zirconium for titanium in Ti-Cr-V alloys has been studied at 303 K. Zirconium substitution decreased the equilibrium pressure and the hysteresis of the P-C isotherm. However, it increased the slope of the P-C isotherm and decreased the hydrogen storage capacity by forming the ZrCr2 phase. By modifying the composition ratio of titanium to chromium, thereby suppressing the formation of the ZrCr2 phase, an alloy having very high hydrogen storage capacity was realized. Heat treatment of the alloys improved the flatness of the plateau greatly without a decrease in both the maximum and the effective hydrogen storage capacities.
